Michael Vick will replace Geno Smith as the New York Jets starting quarterback when the Jets face the Kansas City Chiefs on Sunday, Jets coach Rex Ryan announced Monday.

“We decided to go with Mike Vick this week and give him an opportunity to work extensively with the first-team offense,” Ryan said, “and have Geno take a step back for the first time in his career, maybe get a different perspective of it.

“This is not the long term, this is just on the immediate. My focus is on Kansas City and trying to get a win. That’s why this decision was made.”

Smith threw three interceptions in the first quarter of the Jets’ 42-34 loss to the Buffalo Bills on Sunday and was pulled for Vick after 12 plays.

Smith also suffered a shoulder injury and had X-rays after the game, although the injury apparently was not serious as Ryan said Smith will back up Vick vs. the Chiefs.

Vick completed 18 of 36 passes for 153 yards, throwing an interception and losing two fumbles.

–Jets general manager John Idzik continues to stick by Rex Ryan even as the losses pile up, saying his coach’s job is safe for now.

This comes a day after the Buffalo Bills benefited from six turnovers by the Jets in a 43-23 rout at MetLife Stadium on Sunday, dropping Ryan’s team to an embarrassing 1-7 record with a seventh straight loss.

–The Chicago Bears have lost defensive end Lamarr Houston and left guard Matt Slauson for the season.

Houston suffered a torn right ACL while celebrating a sack of backup quarterback Jimmy Garoppolo during the fourth quarter of a 51-23 loss to the New England Patriots on Sunday. The Bears were losing by 25 points when Houston was injured.

Slauson suffered a torn right pectoral muscle, general manager Phil Emery said.

–New England Patriots quarterback Tom Brady appreciates more than ever his high-profile rivalry with Denver Broncos quarterback Peyton Manning as the two modern marvels face off again Sunday in the twilight of their storied careers.

“Five, six years ago you don’t think about those things,” Brady said in a radio interview with WEEI in Boston. “But as you mature a little bit and realize this could always be the last one, then you do. It’s pretty special.

“(Manning has) been one of the greatest players to ever play. I’ve been fortunate to share a field with one of the best players that has ever played the game. And every time we play a Peyton Manning-led team, it comes down to the wire. Everything is usually at stake.”

–Baltimore Ravens cornerback Jimmy Smith will miss several weeks with a sprained foot, coach John Harbaugh said.

Smith was injured Sunday in the Ravens’ 27-24 loss to the Cincinnati Bengals.

The injury leaves the Ravens scrambling at cornerback, where they have just four players listed on the depth chart.

–The San Diego Chargers reportedly released cornerback Richard Marshall.

Marshall, in his second year with the Chargers, had no interceptions or pass breakups in eight games. His release was reported by Pro Football Talk, which cited a league source.

Marshall committed a 31-yard pass interference penalty that helped lead to a touchdown in the Chargers’ 35-21 loss to the Denver Broncos last Thursday. Marshall also was called for illegal contact on another touchdown drive.

–Brian Quick, the St. Louis Rams’ leading wide receiver, reportedly suffered a dislocated shoulder and torn rotator cuff and is expected to miss the rest of the season.

Quick suffered the injuries on his lone catch in the second quarter of the Rams’ 34-7 loss to the Kansas City Chiefs on Sunday, according to ESPN’s Adam Schefter.

Quick had 25 catches for a team-leading 375 yards and three touchdowns.

The Rams also are expected to be without left tackle Jake Long for the rest of the season after he reportedly suffered a torn ACL.
